And according to Italian daily Il Mattino, question marks over whether Insigne will be able to feature in the game have continued to persist.

The 28-year-old winger picked up a muscle injury Napoli’s 4-3 defeat against Juventus and missed Italy’s European Championship qualifiers.

Napoli have been treating Insigne’s injury with kid gloves and he is undergoing a special program to make sure that he completely recuperates in time for the big Champions League game.

While Napoli are hopeful that the 28-year-old will make it, there are doubts whether coach Carlo Ancelotti will be able to call upon the services of his speedy forward when the time comes next Tuesday.

Insigne has scored two goals and has registered the same number of assists to his name this season in two appearances.
